While building out my hotel development model (currently underway), I decided to take a break and record a video about how I roll up the monthly cash flow line items on my Monthly Cash Flow sheet into annual cash flow line items on a separate sheet using only a single formula and simply copying and pasting that formula across the sheet. If done correctly, this formula can save you a tremendous amount of time.

More often than not, but especially for development models, we need to build out cash flow projections in monthly periods to allow for a more granular analysis and manipulation of cash flows over an investment hold period. However, it is also useful for both yourself and third parties looking at your model to be able to review the rolled up cash flow projections in annual periods as well in order to get a quick snapshot that is more easily digestible and takes up minimal space on a sheet.

Quick Formula for Rolling up Monthly Cash Flows into Annual Periods

There are many ways and formulas that can be used to go about rolling up monthly or even quarterly cash flows into annual periods, but I believe that the formula shared below in the video will be among the easiest and fastest methods out there. In the quick ~7 minute video below, I will walk you through the prerequisite setup needed in your model so that the formula can be implemented, we will then build out the formula, and then finally, copy and paste the formula in the relevant cells in the sheet.

The video recorded below is using my ‘currently underway’ hotel development model, but at the bottom of this post you can find an excel template that has been recreated from the model. You can download that file below by clicking on the link and use it to follow along with the video.
